Hair analysis has gained recognition as an effective method for identifying drug and alcohol consumption. Hair offers an extensive historical record of alcohol and drug intake by embedding biomarkers within the fibers of the growing hair shaft. When obtained near the scalp, hair can furnish approximately a 3-month timeframe for detecting alcohol and drugs. Hair is easy to gather, somewhat hard to tamper with, and simple to transport.
A 1.5-inch section consisting of roughly 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal sample size for both screening and verification. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg of the material is advised. It is suggested to weigh the sample using a jeweler’s scale. If scalp hair is not accessible, an equivalent amount of body hair can be used. When mentioning head hair, we are specifically referring to scalp hair. Body hair pertains to all other forms of hair (facial, axillary, etc.).
Process Overview
The four critical phases in the lab processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary handling of a sample into a laboratory’s system. This includes ensuring the sample was properly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry absent from an electronic chain of custody system.
Screening involves an initial rapid assessment for drug misuse. Although Screening is a cost-effective method to exclude drug use in most samples, a positive screen needs confirmation to be valid in legal proceedings. Any samples with a presumptive positive in Screening necessitate secondary verification.
If a sample shows a presumptive positive in the Screening phase, additional hair is extracted from the initial sample and readied for Extraction. During this phase, drugs are derived from hair at a reduced concentration compared to other methods (e.g., urine or oral fluid), making hair drug screening the most challenging technique to execute.
Verification of any positive screening outcome is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as necessary. The complete laboratory process from Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 accreditation standards.

Note: Although often labeled as "hair follicle tests", the examination itself assesses the hair strand and not the follicle beneath the scalp.

The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.
Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis. The impact of hair treatments on the oxidation/decomposition of drugs in hair was also explored, as the long-term fate of drugs incorporated in the keratin matrix. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.
Forensic Applications and Interpretation: One of the vital objectives of hair testing is its application in forensic investigations and legal proceedings. The SoHT meeting in Verona emphasized the significance of rigorous interpretation of analytical results and the need for standardized protocols. Manuscripts in this section present advancements in forensic toxicology, and have explored the challenges posed by emerging designer drugs and strategies to combat their proliferation. The pitfalls encountered when the exogenous/endogenous nature of a substance is questioned were presented and discussed. The special issue presents also manuscripts that delve into the ethical implications of drug testing in drug facilitated sexual assaults.
Clinical Applications of hair testing are witnessed by the insight on environmental tobacco smoke exposure, assessed by hair analysis in a population of students and the study of in utero-exposure to drugs of abuse through neonatal hair analysis. Exposure to drugs was also important in cases of child abuse/neglect, when the clinical purpose of hair testing merge with its forensic applications.
The legal framework surrounding hair testing and the achievement of guidelines to ensure fairness, accuracy, and confidentiality in drug testing practices have also been discussed,and the SoHT consensus on general hair testing and testing for drugs of abuse was presented at the meeting and published as a Letter to the Editor.
